"Metal Monsters?" Yeah, creatures called Viji. Their distinguishing traits are as follows:
1: Orb-like heads
2: Strong talons (noted for viselike grip and capacity to lock on grasped objects)
3: Bipedal, roughly humanoid bodies
4: Metal plating covering the body, like a knight clad in armor made of giant scales
Viji have human-level intelligence (self-awareness and intelligence akin to a human) and are covered in natural metal armor, yet they live on mountains. This is odd, as:
A) Metal conducts temperate extremely well, and thus would likely leech heat away from Viji to lethal effect (source: in a science exhibit, there was temperature station with a slab of ice and freezing aluminum kept side-by-side. Despite being the same temperature, the aluminum felt colder.)
B) Lightning strikes the closest possible conduit to the ground, metal is pretty conductive, so Viji on mountains need to either live as low as possible or simply adapt to survive lightning strikes. I'm not sure that Viji armor will work as a Faraday cage, thanks to [this question that outlines how lightning will absolutely murder a knight in plate.] 1
So, in essence, my question is What Adaptations Do Viji Need To Survive On Mountains?
Specifications For Best Answer:
The best answer will identify the most likely adaptations for mountain survival, considering both the above issues and whatever other issues would exist for metal-armored, mutated hominids. (Yes, Viji are hominids, just highly modified ones that resemble lizards more than people and incorporate metals they ingest into their body, mainly their scales and claws).
The best answer will also explain why these traits would be selected for, even when Viji aren't necessarily forced to live on mountains. My idea is that if there is sufficient reason for lighting and cold-protecting traits to develop off of mountains, it will happen naturally and then Viji could go to the mountains for greater protection.
Incorporating metal from the environment may seem unfeasible, but the scaly-foot snail proves it's possible. As for what 'plating' means, think pangolin-overlapping scales grown from the skin. These scales are modified bony plates, but the "bone" is reinforced with steel (which I believe is made of a iron-carbon mix) in the place of calcium.
